I am new to QT creator 4. When I create a new project, gives me the option to choose a base class : <
Please clarify in simple words.
Designed specifically for dialog or "pop-up" windows. These are useful for things like communication, open / save dialog, or notification messages generated from your main application.
There is a special widget that has a menu bar, a toolbar and a status bar underlying. This is useful for the main app window to fit the main main window.
Each GUI is the basis of the element, so it is catch-all it is less specific than the other two classes, but in return it is more flexible.
What you should choose should be the best fit. Obviously, the way you write the code will be effective, because they are different classes, but all still are QWidgets.
